Lake Erie Regional Grape Program - IPM Weed Management Links

Demonstrating a Postemergence Vineyard Weed Management Program (I):
Under the row weed management in Lake Erie vineyards have traditionally relied on the use of a pre-emergence herbicide application in the spring followed by an application of a postemergence herbicide in June (or around grape bloom) . . .

Demonstrating a Postemergence Vineyard Weed Management Program (II):
The goal of this project was to implement the post-emergence weed management program in growers' fields to determine if: 1) it fit into a growers schedule of production practices, 2) was economically feasible, and 3) any persistent weed problems would result from continued use of a postemergence weed management program . . .

Exploring Alternative Methods of Implementing Isomate-GBM in High Risk Vineyards:
Alternative management strategies for grape berry moth have been part of Grape IPM implementation and demonstration projects in New York State since 1990. The Grape Berry Moth Risk Assessment (GBM RA) protocol developed by Hoffman and Dennehy, Department of Entomology, NYSAES, Geneva, NY, has since been widely implemented by growers and has been shown to significantly reduce, or eliminate insecticide use for grape berry moth (GBM) in a majority of vineyards in the Lake Erie grape growing region . . .

Reexamination of Grape Berry Moth Management Practices:
Despite wide implementation of the Grape Berry Moth Risk Assessment protocol across the Lake Erie region, late season damage from the second and third generation of GBM has not been accurately predicted. This late season damage has become a concern for 'Concord' growers in the Lake Erie region over the last three growing seasons . . .

Reexamination of Grape Berry Moth Management Practices (II) :
This project was designed to describe variation in spring flight activity, its relationship to the number of generations in a season and to correlate male pheromone trap catches with female activity . . .

Implementing Grape Berry Moth Risk Assessment and Leafhopper Scouting in Lake Erie Region Vineyards:
The Grape Berry Moth Risk Assessment protocol has become an extremely valuable tool in a vineyard IPM strategy. It allows growers to not only apply insecticides only when necessary, but has been easily adopted by growers because of it's ease of use and the fact that it is viewed by growers as relatively low risk . . .

Addressing the Food Quality Protection Act in Lake Erie Region Vineyards:
The implementation of the Food Quality Protection Act (FQPA) could drastically alter pest management strategies currently used by grape growers in New York State. There is a need to develop vineyard pest management strategies that provide growers with the information needed to manage pest populations if conventional pesticides currently in use are lost or restricted . . .

Addressing the Food Quality Protection Act in Lake Erie Region Vineyards II:
The implementation of the Food Quality Protection Act (FQPA) could drastically alter pest management strategies currently used by grape growers in New York State. There is a need to develop vineyard pest management strategies that provide growers with the information needed to manage pest populations if conventional pesticides currently in use are lost or restricted . . .

Grower Adoption of Grape IPM Disease Managment Strategies:
Spray records were collected from 18 of the 26 growers who originally participated in the weather network and applications of fungicides were examined to see how they coincided with infection periods . . .
Scouting took place during the last week of July . . .
